Smartphone Planetarium Design
Modular astronomy instrument built from smartphone sensors. Students assemble, calibrate, and collect data from real celestial observations. Part of astro-lab.app — a running research collaboration across three universities. The student is simultaneously experimenter and instrument maker.
The instrument uses the smartphone camera for exoplanet transit photometry and onboard sensors for orientation and alignment. The measurement is real — not a simulation.
Inquiry-based design: students formulate the observation hypothesis, handle calibration, and identify sources of error independently. Data contributes to a shared cross-institutional dataset.
Low-cost hardware by design. Removing the mystification of scientific instruments is part of the pedagogy — if students can build it themselves, they understand what it measures.
